Definition: A sexual act where a male repeatedly slides his penis in the crease behind the female's (or male's) neck as an alternative to penis to vaginal intercourse. The female (or male) usually has a stiff neck as a result of this act, thus the name, Trashy Whiplash.

Position: The female (or male) gets on her/his knees and cocks her/his head back as far as it can go. The male then puts his penis in the crease formed at the back of the neck.
